Microsoft also provides information to help customers prioritize monthly security updates with any non-security, high-priority updates that are being released on the same day as the monthly security updates. Please see the section, Other Information.

This security update resolves a publicly disclosed vulnerability in Windows Shell. The vulnerability could allow remote code execution if the icon of a specially crafted shortcut is displayed. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

This security update resolves one publicly disclosed vulnerability and one privately reported vulnerability in the Secure Channel (SChannel) security package in Windows. The more severe of these vulnerabilities could allow remote code execution if a user visits a specially crafted Web site that is designed to exploit these vulnerabilities through an Internet Web browser. In all cases, however, an attacker would have no way to force users to visit these Web sites. Instead, an attacker would have to convince users to visit the Web site, typically by getting them to click a link in an e-mail message or in an Instant Messenger message that takes users to the attacker's Web site.

This security update resolves a privately reported vulnerability in Microsoft XML Core Services. The vulnerability could allow remote code execution if a user viewed a specially crafted Web page using Internet Explorer. An attacker would have no way to force users to visit these Web sites. Instead, an attacker would have to persuade users to visit the Web site, typically by getting them to click a link in an e-mail message or Instant Messenger message that takes users to the attacker's Web site.

This security update resolves a privately reported vulnerability in Microsoft MPEG Layer-3 audio codecs. The vulnerability could allow remote code execution if a user opens a specially crafted media file or receives specially crafted streaming content from a Web site or any application that delivers Web content. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

This security update resolves six privately reported vulnerabilities in Internet Explorer. The most severe vulnerabilities could allow remote code execution if a user views a specially crafted Web page using Internet Explorer. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

This security update resolves several privately reported vulnerabilities in Microsoft Windows. The most severe of these vulnerabilities could allow remote code execution if an attacker created a specially crafted SMB packet and sent the packet to an affected system. Firewall best practices and standard default firewall configurations can help protect networks from attacks originating outside the enterprise perimeter that would attempt to exploit these vulnerabilities.

This security update resolves a privately reported vulnerability in Cinepak Codec. The vulnerability could allow remote code execution if a user opens a specially crafted media file or receives specially crafted streaming content from a Web site or any application that delivers Web content. An attacker who successfully exploited this vulnerability could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

This security update resolves four privately reported vulnerabilities in Microsoft Office. The most severe vulnerabilities could allow remote code execution if a user opens or previews a specially crafted RTF e-mail message. An attacker who successfully exploited any of these vulnerabilities could gain the same user rights as the local user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

Vulnerabilities in the Microsoft .NET Common Language Runtime and in Microsoft Silverlight Could Allow Remote Code Execution (2265906)

This security update resolves two privately reported vulnerabilities in Microsoft .NET Framework and Microsoft Silverlight. The vulnerabilities could allow remote code execution on a client system if a user views a specially crafted Web page using a Web browser that can run XAML Browser Applications (XBAPs) or Silverlight applications, or if an attacker succeeds in convincing a user to run a specially crafted Microsoft .NET application. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. The vulnerabilities could also allow remote code execution on a server system running IIS, if that server allows processing ASP.NET pages and an attacker succeeds in uploading a specially crafted ASP.NET page to that server and executing the page, as could be the case in a Web hosting scenario.

Vulnerabilities in Windows Kernel Could Allow Elevation of Privilege (981852)

This security update resolves several privately reported vulnerabilities in Microsoft Windows. The most severe of these vulnerabilities could allow elevation of privilege if an attacker logged on locally and ran a specially crafted application. An attacker must have valid logon credentials and be able to log on locally to exploit these vulnerabilities. The vulnerabilities could not be exploited remotely or by anonymous users.

This security update resolves one publicly disclosed and four privately reported vulnerabilities in the Windows kernel-mode drivers. The most severe of these vulnerabilities could allow elevation of privilege if an attacker logs on to an affected system and runs a specially crafted application. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability. The vulnerability could not be exploited remotely or by anonymous users.

This security update resolves a privately reported vulnerability in Windows Movie Maker. The vulnerability could allow remote code execution if an attacker sent a specially crafted Movie Maker project file and convinced the user to open the specially crafted file. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

This security update resolves a privately reported vulnerability in Microsoft Office. The vulnerability could allow remote code execution if a user opens a specially crafted Excel file. An attacker who successfully exploited this vulnerability could gain the same user rights as the logged-on user. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights.

This security update resolves two privately reported vulnerabilities in Microsoft Windows. The more severe of these vulnerabilities could allow elevation of privilege due to an error in the processing of a specific input buffer. An attacker who is able to log on to the target system could exploit this vulnerability and run arbitrary code with system-level privileges. The attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

Vulnerabilities in the Tracing Feature for Services Could Allow an Elevation of Privilege (982799)

This security update resolves one publicly disclosed vulnerability and one privately reported vulnerability in the Tracing Feature for Services. The vulnerabilities could allow elevation of privilege if an attacker runs a specially crafted application. An attacker must have valid logon credentials and be able to log on locally to exploit this vulnerability. The vulnerability could not be exploited remotely or by anonymous users.

Microsoft provides detection and deployment guidance for security updates. This guidance contains recommendations and information that can help IT professionals understand how to use various tools for detection and deployment of security updates. For more information, see Microsoft Knowledge Base Article 961747.

Microsoft Baseline Security Analyzer

The Microsoft Baseline Security Analyzer (MBSA) allows administrators to scan local and remote systems for missing security updates as well as common security misconfigurations. For more information about MBSA, visit Microsoft Baseline Security Analyzer.

Microsoft Systems Management Server (SMS) delivers a highly-configurable enterprise solution for managing updates. By using SMS, administrators can identify Windows-based systems that require security updates and to perform controlled deployment of these updates throughout the enterprise with minimal disruption to end users. The next release of SMS, System Center Configuration Manager 2007, is now available; see also System Center Configuration Manager 2007. For more information about how administrators can use SMS 2003 to deploy security updates, see SMS 2003 Security Patch Management. SMS 2.0 users can also use the Security Update Inventory Tool (SUIT) to help deploy security updates. For information about SMS, visit Microsoft Systems Management Server.

Note SMS uses the Microsoft Baseline Security Analyzer to provide broad support for security bulletin update detection and deployment. Some software updates may not be detected by these tools. Administrators can use the inventory capabilities of SMS in these cases to target updates to specific systems. For more information about this procedure, see Deploying Software Updates Using the SMS Software Distribution Feature. Some security updates require administrative rights following a restart of the system. Administrators can use the Elevated Rights Deployment Tool (available in the SMS 2.0 Administration Feature Pack) to install these updates.

Update Compatibility Evaluator and Application Compatibility Toolkit

Updates often write to the same files and registry settings required for your applications to run. This can trigger incompatibilities and increase the time it takes to deploy security updates. You can streamline testing and validating Windows updates against installed applications with the Update Compatibility Evaluator components included with Application Compatibility Toolkit.

The Application Compatibility Toolkit (ACT) contains the necessary tools and documentation to evaluate and mitigate application compatibility issues before deploying Microsoft Windows Vista, a Windows Update, a Microsoft Security Update, or a new version of Windows Internet Explorer in your environment.
